our kits. This is why we recommend using our RRD Racing shocks or the provided
Bilstein part numbers)

NOTES!
- We typically recommend 4.5in of back spacing on rims for 33in and 35in tall tires.
- We typically recommend 3.5in of back spacing on rims for 37in tall tires.
- For 2012 and newer models an aftermarket front driveshaft with 2in O.D. steel tubing is recommended, but not required.
- The X Factor System allows the rear axle to be pushed back up to 1in over stock which perfectly centers the rear axle assembly under typical aftermarket flat fenders. It also allows for larger tires without contacting the rock sliders or rear pinch seam.
